About this Research Topic
Li metal anode is an ideal anode choice for lithium batteries anode due to its high specific capacity (3860 mAh/g) and the lowest operation potential. However, the dendrite issue of Li metal raises safety concerns due to the potential short circuit. As a result, the replacement of Li metal with graphite anode led to the triumph of lithium ion batteries in early 1990s. However, the ever-expanding market of energy storage in portable electronics and electric vehicles arouses a surge of interest in revisiting high energy density metal anodes in battery applications. Therefore, the developments as well as new understandings of these metal anode (e.g. Li, Na, Zn, and Mg) are urgently required.
For Li metal anode (LMA), dendrite issues and low Coulombic efficiency have been widely recognized as two main challenges to hinder its practical applications. To address these issues, many strategies including electrode design, electrolyte modification and separator engineering have been explored for a stable LMA. Despite the exciting progress made in the past few years, the complex batteries' operation conditions such as cathode materials, electrolyte components, operation temperature and current density, require deep investigations of these metal anodes. Given this situation, this Research Topic will particularly focus on the progress and investigations of high energy density metal batteries systems.
